Of course, their explanation is garbage. You want the field to compress the plasma. The fusion yield goes as n^2*V, which is the density times the particle inventory. All other things (in particular the particle inventory and temperature) being equal, big and tenuous should give you less neutrons than small and dense. That shouldn't surprise anybody. Lerner has never been a big fan of physics constraints like equilibrium.

I think it is trying to say that the rotation helps form a bigger plasmoid of the same density, not a more tenuous one of the same inventory.

Is there any acknowledged physics at all behind this "dense plasma fokus"? Or are we dealing with a bunch of howling lunatics in urgent need of heavy medication?

You can definitely make a decent plasmoid this way. Where Lerner goes crazy is thinking that the field can twist around in such a way as to produce a small but extremely dense plasmoid - in violation of the virial theorem.
